大头鳄属（学名：Pholidosaurus）是鳄形超目新鳄类大头鳄科的一属，是大头鳄科的模式属。化石发现于德国、英格兰，生存年代估计约为白垩纪早期的贝里亚阶。发现于瑞典斯科讷、丹麦博恩霍姆岛的中真鳄类化石，可能也属于大头鳄属。

根据理乍得·莱德克（Richard Lydekker）在1887年的研究，大头鳄的眼眶略小于颅顶颞上窝（Supratemporal fossa）、前上颌骨接临鼻骨、犁骨位于腭骨上方。大头鳄的外表、体型接近现代长吻鳄。大头鳄具有长口鼻部，而多次与森林鳄科、海鳄亚目被归类于相同演化支，实际上是个别平行演化的结果

Pholidosaurus is an extinct genus of neosuchian crocodylomorph. It is the type genus of the family Pholidosauridae. Fossils have been found from Germany and England. The genus is known to have existed during the Berriasian stage of the Early Cretaceous. Fossil material found from the Annero and Jydegård Formations in Skåne, Sweden and on the island of Bornholm, Denmark, have been referred to as a mesoeucrocodylian, and possibly represent the genus Pholidosaurus.
